thank you so much to all of you. Dennis, thanks for correcting the problem. yes, I thought there was something wrong with the structure. just one question to either you or Jeff
after studying what Jeff so extensively explained, I can not figure out this 82+ d = 125. (D ???)d= 12 why 12? what is the value of d?

thank you so much for everything. I will continue to study hard, but I know you will have to keep on helping me. I like math but I struggle with a lot of deductions. it takes practice and a lot of thinking'.
but I know I can count on you.
this esol degree represent s a lot for me and my family. we are struggling financially and I have to ace that math test. got no other option, and have 10 months to take the math test.

and lastly, where did the 43 come from?

No, d is not equal to 12. Just think about this practically, as though you were actually paying your phone bill. You get a bill. You know that the bill costs at least $82.00, which is the base charge just for having a phone at all (b). However, in this particular month the total bill has come out to more than that: $125. The difference between these two amounts ($125 - $82 = $43) is equal to the extra charges you had on your bill for this month (charges over and above the base rate). Since the only source of extra costs mentioned in the problem is data usage, you know that this $43 is how much extra you were charged on the bill for your data usage this month. That's where the d = $43 comes from.

As defined by JeffM, "m" is the man's share of the bill. Since the man and woman are splitting the bill, their two shares have to add up to the total bill amount:

You need to know what 82+ d = 125 is asking. It is asking 82 plus what number (denoted by d) equals 125. Of course d is not 12 just because 82 + 12 is not 125 (it is 94). Keep on trying as you can do it.
